Abstract
Disclosed herein is a data storage device. A data port transmits data between a host computer system and the data storage device. A non-volatile storage medium stores encrypted user content data and a cryptography engine uses a cryptographic key to decrypt the encrypted user content data stored on the storage medium in response to a request from the host computer system. An access controller receives a request from a manager device to initialize the data storage device. The controller generates the cryptographic key, generates a manager key configured to provide manager access for the manager device and provide access to the cryptographic key, and stores, on a data store, authorization data indicative of the manager key and accessible based on a private key stored on the manager device.
